SLIDING WINDOW.

Application filed March 5, 1926.

This invention relates to sliding windows and has for its principal object to provide a novel sliding window which is constructed to positively exclude the entrance ot either rain or wind around the bottom of the window thus making a waterproof and airtight window.

@ther objects bi' the invention are to iinpr ve sliding windows in otherrespects all as will be more 'fully hereinafter set forth.

ln order to give an understanding of the invention l have illustrated inthe crawings a selectedembodiment thereorF which will new be described after which the novel teatures will he pointed out in the appended claims.

Fig. 1 is a section through the stool olE the window frame and the two sashes thereci' v Fig. 2 is a horizontal section on the line 2--2, Fig. 1; y

3 is a section on the line 3-8, Fig. 1;

Fig. 4 is a detail showing the manner in which the rendl of the outer guard rail is secured;

Fig. 5 is a section on the line .fi- 5, Fig. 3.

Referring to Fig. 1 of the drawings 1 indicates the stool or lower member of a window frame on which the sliding windows rest. rlhe sliding sashes, two oi which are shown, are' indicated at 3 and 4 respectively. 5 indicates the stool cap on the inside of the window frame, 6 indicates the studding olf the building and 7 the sheathing or finish.

rlhe present invention relates particularly to the construction of the stool and the lower sash by which a water-tight and air-tight window is produced. The stool is provided with two tracks 8 and 9 on which the two sashes 3 and 4 rest and slide. The outside track 9 is situated below the inside track 8 as indicated and each track is formed by a metal plate which is screwed to the stool by means of suitable screws 10.

Each sash is provided in its lower edge with rollers 11 which rest on the tracks thereby facilitating the sliding movement of the sashes. The inner face of the lower sash 3 rests against the outer edge of the stool cap 5 and is retained in this position by means of an inside guide rod or parting member 13 which is in the form of a rod that is secured at its ends to blocksy 14 that are located at the opposite sides of the window frame and at its central portion is supported by rests 15.

Serial No. 92,398.

The outer sash 4 is retained in position on the track 9 and in engagement with the parting red lil by means of a guide rod 16. llach end oi the rod 16 is reduced in dia. ter as shownat 17, (see Fig. 4), and the reduced end enters an aperture formed in a plate 18 which is secured to the side of the window Jiframe. The rod 16 is supported intermediate of its ends by one or more rests 19. t

loih. the rests and the rod are retained inplace by screws 20 which pass through the red and rest and screw into the stool. f

ln order to provide a water-tight and wind-tight window the lower rail of each sash is formed on its inner edge with a horizontal groove in which is received the edge ci a plate. The groove in the inner sash 3 is indicated at 21, it being situated. slightly above the bottomo'lc the sash. rlhe corresponding groove in the outer sash 4 is indicated at 22.

23 indicates a plate which is secured bctwecn the stool cap and the stool and the outer edge of which extends into a groove 21.

`The track 8 is made wider than necessary to receive the inner sash 8 and they outer edge 24 thereof extends into the groove 22. The plate .J3 and the edge 24 of the track 8 constitute protector plates which by their entering the grooves 21 and 22 form both a water-tight and air-tight connection between t3 C the sash and stool and prevent any rain from being` driven in under the sash and also exclude any wind at this point.

It will he noted that the guide members 13 and 16, being supported on the rests 15 and 19, are thus located above the stool, the purpose of this being to permit any rain or water to readily drain oil' from the stool. This construction avoids any grooves or pockets in which water might accumulate.

rlhe sides 25, 26 of the two sashes which meet each other when the window is closed are arranged to overlap as indicated at 27 thereby making a stormetight joint at this point. At the lower ends these sashes are cut away to receive the parting rod 13, as shown in Fig. 5, and a rest 15 is provided at this point to lill the space beneath the rod when the windows are closed.

l claim:

1. In a sliding window, the combination with a window stool having outer and inner tracks each formed by a metal strip, the outer track being lower than the inner track,

an inner and an outer sash slidable on said tracks, the inner tace oi the lower rail oi' the outer sash having` a horizontal groove and the outer et ge oi the strip forming the inner track extending beyond the outer tace ot said inner sash and into said groove thereby making a tight joint.

2. In a sliding window, the combination with a window stool having outer and inner track-s each formed by a metal strip, the outer track being lower than the inner track, an inner and an outer sash slidable on said tracks, the inner tace or the lower rail of the outer Isash having a horizontal groove and the outer edge o' the strip forming the inner track extending beyond the outer tace oit said inner .shaft and into said groove thereby making a tightioint, and the lower rail ot the inner sash also having a horizontal groove, and a protector plate secured to the window stool and entering said last named groove.

3. In a sliding window, the combination with a window stool having inner and outer tracks, the outer track being lower than the inner track, a window sash slidable on each track, a parting rod secured to the stool and situated between the sashes, said rod being spaced troni the stool to permit drainage.

t. In a sliding window, the combination with a window stool having inner and outer tracks, the outer track being lower than the inner track, a window sash Islidable on each track, a parting rod secured to the stool and situated between the sashes, said rod being spaced from the stool to permit drainage, the lower rail of each sash having on its inner face a horizontal groove, and a protecting plate entering' each groove and forming a waterand wind-tight joint.

5. In a ysliding' window, the combination with a window stool having an inner and van outer' track, the outer track being at a lower lever than the inner track, an inner sash sliding on the inner track, an outer sash sliding on the outer track, a parting rod secured to the stool .but spaced therefrom and situated `between said sashes, and a guide rod also secured to the stool and engaging the outer tace of the lower sash, said guide rod being spaced from the stool to permit drainage.

6. In a sliding window, the combination with a window stool having outer and inner trac is each formed by a metal strip, the outer track being lower than the inner track, an inner and an outer sash slidable on said tracks, a parting member separating the lower rails of the two sashes, said parting member being spaced above the tracks, the inner tace or the lower rail ot the outer sash having a horizontal groove and the outer edge ot the strip 'forming the inner track entending beyond the outer face of said inner rail and underneath the parting member and into said groove thereby Inaking a tight joint.

In testimony whereof, I have signed my name to this specification.
